Our Review of the Suunto Core

The Suunto Core is the benchmark of Suunto's ABC (Altimeter, Barometer, Compass) wristop computers, furnishing the best features of top-selling Suunto predecessors, and then advancing upon their legacy with innovative environmental monitoring functions that any outdoor adventurer will find invaluable. The Suunto Core is the culmination of years of testing, research, user feedback from the field, and technological advancements in the Suunto laboratory.
In addition to its legendary Suunto capabilities, the Suunto Core epitomizes the latest advances in the Suunto aesthetic, coming in a stunning array of colors and configurations - from basic yellow-on-black to lustrous steel-on-steel. There's also a diverse selection of replacement straps that allow you to further customize the look and feel of your stylish new ABC wristop.
Ascending a mountain peak? Making a boardroom speech? Either/Or, there's never a need to remove your Suunto Core.
More than just a pretty face: The Suunto Core has been awarded prestigious Gear of the Year 2007 award from Men's Journal magazine.

Suunto Core Reviews
It
awesome
Almost return Core. Thanks.
Good, but...
Comments from The Staff:
Thanks for the feedback - good stuff. Sorry to hear about the issue with that button. Unfortunately, a number of issues did surface with some of the watches from the initial production runs, but my understanding is that the issues have been addressed and current-production Cores incorporate improvements driven by comments like yours. I certainly hope your replacement operates better than your first one - I'm confident it will be problem-free. Thanks again.
